Rushed behind
I don't see these as a huge problem. If the change was small - say making the defender have to wait until the goal umpire waved their flags - I would be fine with it. But I'm leery with changes that rely on umpire interpretation. And the moment its simple, did a forward kick it? If not, its a behind. This would put a lot more grey into it, and umpires are human and make mistakes.
So I'd probably say no, or at least a small change.
Totally agree with this.
